The PE 73 temperature protection device is used to shut off the sample flow in the event that the sample temperature rises above an adjustable switching point due to a lack of cooling water.
The electric ball valve PE 73 operates by means of control by the temperature switching device PE 79 Temp Control. For measuring points with low operating parameters, a solenoid valve can also be used for cost reasons, which is closed without current.
- High torque enables use even above 200bar
- Evaluation by switching contact
- freely programmable switching point
- Local reset at Temp Control PE 79
Safety shut-off systems are used to shut off the sample flow when the sample temperature is too high, such as when the cooling water fails or when the sampling cooler is defective. They prevent extremely hot sample material from flowing through the measuring instruments and destroying them or injuring operating personnel.
PE 74
AutoSafe mechanical safety shut-off system. It uses a thermostat system for the switching operation and is therefore independent of a power supply. It can be used for pressures up to 300 bar. A signal contact for fault indication or as a switching contact is available as an option.
PE 79
Electronic temperature switching device TempControl. The TempControl detects the temperature at the sample outlet and activates the associated safety shut-off system when a freely selectable limit temperature is exceeded. The system remains closed until the fault has been rectified and the corresponding acknowledgement has been received. During the fault, a potential-free contact signals a corresponding alarm.
PE 73/79
Elektrisch angetriebener Absperrkugelhahn mit Temperaturschaltgerät TempControl. Das klassische Absperrsystem mit Schließzeiten < 15 s ist für den Einsatz im Hochdruckbereich bis 400 bar geeignet.
Alternativ können außerdem Pneumatikventile (Druckluft gesteuert) mit Schließzeiten < 1 s eingesetzt werden.
PE 76/79
Solenoid valve with TempControl. For use in the low-pressure range for pressures below 40 bar.
(Also available for high temperature range)
